[Buildroot] [PATCH] support/scripts/boot-qemu-image.py: pexpect must throw an exception when a timeout occurs

[Yann E. MORIN <yann.morin.1998@free.fr>]

romain, All,

On 2021-02-20 17:56 +0100, Romain Naour spake thusly:
> As reported on IRC by sephthir, the gitlab test of the defconfig
> qemu_sparc_ss10_defconfig doesn't error out while the system
> is not working properly.
> 
> This is due to pexpect doesn't throw an exception when a
> timout occurs and continue to the next command.
> 
> Remove "pexpect.TIMEOUT" to get the expected behaviour.

The commit log up to that point was a bit fuzzy about why that was the
case, and the commit title was not very clear either, so I reworded it.

> The qemu_sparc_ss10_defconfig is already fixed by
> 4d16e6f5324f0285f51bfbb5a3503584f3b3ad12.
> 
> This was reported to gcc upstream:
> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98784

This reference does not belong to this commit (it is about the failing
defconfig itself,m not about the failure of our infra), so I dropped it.

Applied to master, thanks.

Regards,
Yann E. MORIN.
